Since my undergraduate studies in Peru, my own curiosity has led me to conduct smaller research projects, and yet they have given me experience with topics as diverse as flora inventories in rain, cloud and high Andean forests, all over Peru and Bolivia. This has given me a broad knowledge of tropical and Andean ecosystems. Research related to the impacts of climate change on biodiversity on the Tropical Andes has allowed me to be aware that the tropical Andes are one of the top biodiversity hotspots on the Earth and the integrity of these ecosystems is seriously threatened by climate change and land‐use changes. Thus, conservation strategies need to be adapted to the rapidly changing environment, and new strategies such as adaptive management schemes need to be developed that specifically address climate change impacts on biodiversity, ecosystems, and human well‐being. Acquiring a broader knowledge of tropical Andean ecosystems led me to participate in an initiative for the evaluation of tree species of the tropical Andes within an international group of researchers from around Latin‐American.

The genus Polylepis (Rosaceae) is distributed along the Andes from Venezuela to Chile and Argentina. Ecologically and economically, this is one of the most important Andean tree genera. Polylepis forests are the most endangered ecosystems in the Andean highlands. Taxonomically, Polylepis is difficult because on the one hand many species are morphologically quite similar while on the other hand there often is considerable morphological variation within species. This variation can be found both within populations, for example if the plants grow in microhabitats with different water supply but also between geographical populations of the same species. Integrating the strengths of morphological data with those of DNA sequence data in the context of molecular phylogenies is a most fruitful approach to explore the relationships in a group of organism. In addition by incorporating a phylogeographic approach it is possible to infer the evolutionary history of the study group. However, if the emerging pattern shows incongruence between morphological and molecular data, it could suggest that morphological data contain a mixture of homologous characters or there is much phenotypic variation within each species of the study group. Thus, mismatching phylogenies could be caused by either selection or genetic drift. To test these hypotheses, molecular and morphological phylogenies of a group of Polylepis will be reconstructed and compared.
